※ 引述《bc5678 ( )》之銘言： : 摘自 Expert C Programming - Deep C Secrets中的一段 : Like the Potrzebie system, the joke about programmers' confusion over : Halloween and Christmas Day depends on inside knowledge of numbering systems. : The reason that programmers can't tell Halloween from Christmas Day is : because 31 in octal (base eight) equals 25 in decimal (base ten). More : succinctly, OCT 31 equals DEC 25! : When I wrote to Professor Knuth asking his permission to tell the story, and : including a draft copy of the chapter, he not only agreed, he marked numerous : proofreading improvements on the text, and pointed out that programmers can't : distinguish NOV 27 from the other two dates, either : 來源: http://my.safaribooksonline.com/0131774298/ch08 : OCT 31和 DEC 25的關係是很清楚 : 不過Knuth講的NOV 27就看不出端倪了, 上面兩個跟感恩節有啥關係 : 難道是念數學的人才看得懂的joke? 英文月份 October 本來應是8月, November 9月, December 10月 OCT 31 = Nov 27 = DEC 25, 因為八進位31和十進位25換算為九進位,就是27. -- 話說十進位25唸成「二十五」,那麼八進位31是否該唸成「三八一」? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.231.64.207 ※ 編輯: yauhh 來自: 61.231.64.207 (04/26 19:40)
